Please advance your pickets for purposes of observation as far as may be,
in order to obtain timely information of their approach.

Brigadier-General and Aide-de-Camp.


Although addressed to Slocum as well as Howard, this order scarcely
applied with much force to the former, who occupied the right centre of
the army, with Birney lying between him and the Eleventh Corps. Howard
carried out his part of these instructions as well as circumstances
allowed. He posted Barlow's brigade, his largest and best, on the
Buschbeck line, in position for a general reserve for the corps, and
took advantage of the ground in a manner calculated to strengthen his
flank, and to enable it to cover a change of front if necessary; he
placed his reserve artillery on the right of the rifle-pits running
across the road at Dowdall's; he located several regiments on Dowdall's
clearing so as to wheel to the west or south as might be required; Major
Hoffman was set to work, and spent the entire day locating and
supervising the construction of field-works; and generally, Howard
disposed the forces under his command after a fashion calculated to
oppose a stubborn resistance to attacks down the pike, should they be
made.

Later on in the day, we have seen how Hooker's aide, Capt. Moore,
ordered this brigade of Barlow's away from its all-important position.
We have seen Hooker's dispositions of the Third and Twelfth Corps.
We have seen Hooker's 4.10 P.M. order to Sedgwick. No room is left to
doubt that Hooker's opinion, if he had any, underwent a change after
issuing these instructions, and that he gave up the idea of an attack
